EYELETlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 673,815, dated May '7, 1901.

Application filed December 31, 1900. Serial No. 41,611. (No model.)

To all whom it nuty concern:

Be it known that I, PERLEY.R. GLASS, of Quincy, county of Norfolk, and State of Massachusetts, have invented an Improvement in Eyeleting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The present invention relates to an eyelet- IO in g-machine, and is embodied in a machine in which a number of eyelets are set at one operation, the machine being mainly intended for use in eyeleting shoe-uppers, all of the eyelets along one edge of an upper being set at once.

The present invention relates mainly to novel means for gaging or positioning the rnateria1,whereby the two sides of the upper may be consecutively operated upon and the eyelets properly spread on each upper-that is to say, the row of eyelets inclined from the edge of the upper toward the front portion thereof. p

The invention further relates to certain novel details of construction and arrangement, whereby the operating parts are readily interchangeable, so that the same machine may be used on different classes of work involving variations in the spacing of the eyelets, spread of the eyelets, size of the holes, due.

The machine embodying the invention is provided with a gang of punches which cooperate with an anvil or support to punch the material, a gang of setting devices corresponding with the gang of punches to set the eyelets in the holes previously punched, and

a feed-chute having a gang of raceways to supply eyelets to the several setting devices.

In accordance with the invention the machine is provided with a work-support or table having an opening for the members which punch the holes and set the eyelets and a gage or positioning device for the edge of the upper, which gage is capable of being shifted or oscillated to a predetermined extent, so as properly to position the right and left hand sides of the upper consecutively, the endwise position of each upper being determined by another gage.

The punches and setting devices are mounted, respectively, on blocks removable from their supports or carriers, so that if the style of work is to be changed these parts can at once be removed and replaced by others, the anvil and raceways being also interchangeable.

Figure 1 is a side elevation, partly in section, of a machine embodying the invention; Fig. 2, a partial front elevation, also partly in section; Fig. 3, a plan view of a portion of the machine to show the support for the material; Fig. 4, a sectional detail showing the removable carrier for the setting devices, and Figs. 5 and 6 details upon a somewhat larger scale to show the action of the gage.

The punches a, which have tubular cutting portions and annular clenching portions, so as not only to perforate the material, but to cooperate in the eyelet-setting operation, are mounted in an overhanging projection A of the machine-frame A, the gang of punches being permanently connected with a block a removahly secured to said projection A so that one set of punches can be removed and another substituted without diliiculty. As herein shown, Fig. 2, the overhanging projection A is provided with a transverse projection A adapted to enter a slot a in the block a which projection determines the 1011- gitudiual position of the block, and the said block is locked in place by means of a pin or screw A, adapted to be passed through suitable openings in the frame projection and the block o The anvil or cooperating punching member b is removably secured, as by nuts 19 upon a pair of struts b pivotally connected at their lower ends with levers b, which may be operated in any suitable or usual way, as by ac? centrics b on the main shaft B. The struts 0 b are shown as provided with studs b, which enter curved slots 6 in guide-wings b secured to or formed in the frame of the machine, so that as the said struts recede from the punches after the anvil has been forced 5 up against the same the said struts and anvil will be moved laterally to swing out of the Way of the setting devices 0, which then travel upward, each taking an eyelet from one of the raceways d of the eyelet feed 10o chute d and carrying the said eyelet up toward the material in which the several eyelets are all set at once by the cocperation of the sett ing devices 0 with the punches (t.

The setting devices 0 are mounted on a supporting-block 0 which is removably secured to a carrier a movable in guides 0 said carrier having an operating-lever 0 shown as operated by means of the eccentric c. When the style of work is to be changed, the gang of setting devices may be bodily removed and another gang corresponding to the right punches substituted, any convenient kind of fastening devices being employed.

As herein shown, Fig. 4, the block which forms the immediate support for the setting devices 0, is provided with a threaded stem 0 adapted to enter a slot 0 in the carrier 0 thus properly centering the block, and the said stem is provided with a tapered nut 0 which will engage the walls of the slot and lock the support 0 in.place.

The feed-chute d, which is carried by a reciprocating slide 01 is removably connected with said slide, as by nuts (1 so that when a change is made in the punches and setting devices the feed-chute can be easily removed and replaced by another. To support and position the material to be operated upon, the machine is provided with a table or 'worksupport 6, shown as secured by nuts 6 upon supports 6 the said table being located between the punches and the anvil and setting devices. The material upon said table overlies an opening 6 of the proper size and shape to permit the anvil and the setting devices to pass through the same toward the punches, and the said material is properly located by means of a gage. I

In working on shoe-uppers it is usually customary to set the eyelets so that those at the forward or toe end of the upper are somewhat farther from the edge than those at the rear or ankle end, the eyelets in, the finished shoeupper being spread apart at the toe end of the upper. It is necessary, therefore, when the eyelets are to be set in this way that the two sides of an upper should be gaged differently with relation to the punches and setting devices, and to this end the gage embodying the invention comprises a member pivoted at a point substantially midway between the ends of the rows or gangs of tools and adapted to conform to and extend some distance along the edge of the upper, preferably along so much of said edge as is adjacent to the line of eyelets, the extent of pivotal or oscillating movement being determined by stops j herein shown as screws or bolts, threaded in lugs f so as to be readily adjustable to vary the amount of pivotal movement of the gage. In eyeleting one side or member of a shoe-upper, therefore, the operator presses the said upper against the gage, turning said gage in the proper direction until it is arrested by one of the stops f which will cause the line of eyelets to bear the proper relation to the edge of the upper. In eyeleting the other member of the upper the operator turns or oscillates the gage in the opposite direction, so that both sides of an upper can be consecutively eyeleted on the same machine.

To determine the proper endwise position of the uppers, the feed-table e is provided with two adjustable gages 9, shown as mounted on rods g held in suitable socket-pieces g by means of set-screws 9 The said gages are so arranged as to position the top edge of the shoe-upper, one gage serving for one member of the upper and the other gage serving for the other member thereof.

As shown in Fig. 5, the left-hand member of a shoe-upper (inverted) is shown as in position to be operated upon, the gage f being turned so as to engage the stopf at the right, so that the toe portion of the upper is somewhat farther from the line of punch-holes than the ankle portion thereof. When the other side of the upper is placed in position, as shown in Fig. 6, and the gage oscillated in the opposite direction, the line of holes will bear a similar relation to the edge, the result being that in the finished upper the eyelets are spread at the lower end. It is obviously immaterial how or on what part of the machine the gage is supported, provided that the necessary movement is obtainable to accomplish the purpose described. It might, for example, be practicable to mount the worksupport itself on a pivotal support or otherwise provide for a movement thereof to gage the uppers, as described. The machine is also provided with means for adjusting the gage to vary the distance from the edge of the upper at which the eyelets areto be set, the worksupport itself being shown as adjustable for this purpose, as by the slots 6 through which the upper ends of the supports 6 extend. By loosening the nuts 6 the work-support and gage can be moved toward or away from the punches and sets, the opening 6 being wide enough to admit of such adjustments as may be necessary.

In order to spread the eyelets as described, the line of punches is shown as curved slightly; but if the spread is not desired the punches and sets may be removed and replaced by others arranged in a straight line and the gage anchored or made stationary by a proper adjustment of the gage-stops.

It will be seen from the foregoing description that the specific construction and arrangement of the several instrumentalities may be varied or modified without departing from the invention, and it is not intended to limit the invention to the specific construction shown.
